- APrLiANcn'FoR CLEANING WIND-SHIELDS on Moron-immense Application filed April 3, 1912. Serial No. 688,320;

To (ZZZ whom it may concern:

Be 1t known that I, HEINRICH 'Pn non or.

Pnussn residing at Kiel, Germany, have invented certain new and, useful Improve= Inents in Appliances for Cleaning Wind- Shields on Motor vehicles, following is a specification.

In motor vehicles a transparent screen consisting-as a vrule-of a framed pane of glass is usually provided forthe prote'ctio'n of the driver, in froi'it of the drivers seat.

' Besides acting .as a wind shield, italso xshields'are known in the art.

serves for protecting the driver. from dust, rain and snow. The serious disadvantage of'suchshields is thatdirt and dust collecting on the shield impair the clear vision and that the rain drops, after striking the, shield are flattened out-by the windpressureand moved aboutlon' the shield surface, so that in most instances vision through the shield is impossible", lfpropose 'to remedy this defect by providing wipers,',either on one-or on both sides of the stroke of the/driver may be moved over the glass to removethe adherent di' st and water therefrom. Devices for wiping off glass The particularadvantage of my novel device over those known, however, is

pressed against the glass without particular effort of the operator to that effect.

I have illustrated'my novel device in the accompanying drawings, in which,

' Figure 1 illustrates the. guiding device for the glass cleaner in connection .with which .ball bearings are employed, the device being shown partly in longitudinal section. Fig. 2 is a general view. 111' perspective of the cleaning device. Fig. 3 is a horizontal section of the device shown in Fig. 2. Fig.4 is, a si le elevation thereof showing the posiwith the wiper in the position of rest. Fig. 5 is-a similar view,,the wiper jbeing moved downward. Fig. .6 is the same view as that shown in Fig. 4-, the wiper heing'nioved upward. Fig. I

The sleeve (1 asfw Fig. 1, is provided at each end with a ball bearing u. Each. of these hea adjusted by means of a screwfco cap 11 that the hall'sare clamped more 01-- less against the guide rod 6.; a j

In view of the fact that the guiding'of; the sleeve a is effected mainly through the ball bearings, the bore of thegsle eve may he made considerably largertha'n zwqnld be -'resection of th e guide rod I 6. Thus dirt anddust which l'might get be-' will hot impede the movement of'the sleeve on the; rod. T0

The latter rod is ofg shforterlength and car? v" ,ries on its end a guide roller 12-, by means of which itrests on the inner surface of the glass. The handle on .rodd and it engages by means'of'its.

.finger h in a notched arm. is rigidly connected with rod (7 and thus withjthe wiper. will now be seen. that when sleeve r moved down and I up again on rodg" is pivotally. dispos against the u perbearing at means of handle g and the latter'is thereby antomaticall with a catch t provided near the'uppere v geof the screen frame 3. Pawl n carries a pin 0" which engages with. an.

abutment mounted on plate It, when handle 9' s tilted into the position shown in Fi 5, and thereby disengages pawl n from its catch t. v The device actsas follows: When the device is in the position of rest the handle.

'g stands straight at right angles to the glass as shown in Fig. 4, as does also the notched plate 7:. When the wiper is used, the handle g' is pressed downward in the direction of the arrow, aszshown in Fig. 5. Abutment p presses against the pin 1* of pawl n and pushes it away from thecatch t, so that. the cleaner can be moved freely downward. At. the same time the wiper -.f' lies against the glass 8 so that, when the device is drawn down by means of the handle 9'. water and grit are ushed downward and the glasscleane When the handle g is turned up again thewiper f" is removed from the glass 8. and the other wiper f placed on the'glass, as shown in Fig. 6. If the wiper be'now pushed up'by means of the handle a further cleaning or polishingof the glass is effected, and again by means of a pushing movement. When thecleaner for example has reached the upper edge of the glass, the pawl-engages .the catch, whereby the deviceis' prevented from moving downward when the handle is released.

Atthe same time the guidesleeve, a'on the verticaI guide rod 6 pushes L so that the wiper cannot emoved up any iarther;
